We have Integrated ERP with EPM (EPBCS) using Data management. And also we load the metadata and data from ERP to EPBCS. The issue what I am facing here was " Drill through to source is not working from Planning Web Form . We can able to view the form Screen while doing Drill Through but there is no data in that screen.

when I click on Drill through to source then I find error which is below

Actually I enabled drill region in Data management→workflow →data load rule→Target Option.
also enable in Data management→setup →Targete Application→Application option.
For your kind information, Drill through from ERP to EPBCS is working fine and also we can able to view the data in Drill Through page in Data Manegement. And also we changed the Target Dimension Class as Scenario instead of GENERIC in Target Application while doing application registration.
